The missing PRD isn't a documentation problem. It's a decision-ownership problem.

When a product team does not have a PRD, the instinct is to write one.

That can be the wrong first move.

The absence of a PRD is usually not only a documentation gap; it is a signal that the decisions required to write the document have not been made clearly enough, owned explicitly enough, or transferred cleanly enough for someone else to build from them.

A PRD is not the work; it is the record of the work.

It should capture what the feature is for, who it is for, what problem it solves, what success looks like, what constraints matter, which edge cases are in scope, and which decisions should guide implementation when the developer reaches a choice point.

If those decisions do not exist, the document becomes a PRD-shaped object: it sits in the right folder, uses the right headings, and gives the team the comfort of process without carrying the reasoning the product needs.

The failure usually appears later.

A developer starts building and reaches a choice point. The PRD describes the desired outcome, but not the decision logic behind it. The developer makes a reasonable interpretation and moves on. The feature ships, and it is not quite right in a way that traces back to the missing decision, not the missing document.

The PRD existed, but it did not help.

The real problem was decision ownership. Someone needed to own the feature deeply enough to say what it is for, what it is not for, which tradeoffs matter, how the states behave, where the edge cases live, and what the development team should do when reality does not match the happy path.

That ownership cannot be substituted with a template.

Templates are useful when the thinking is already there. They create consistency, force useful prompts, and reduce the chance that important sections get missed. They do not decide the product for you.

This is why I get cautious when teams ask for better PRD formats before asking who owns the decisions inside the PRD. The format might need work, but the deeper issue is usually that decision authority is distributed, assumed, or avoided.

The fix is to assign decision ownership before asking for documentation.

Who is responsible for specifying the feature completely enough that someone else can build it? Who decides what happens in the exception case? Who resolves ambiguity when design, engineering, operations, and business goals pull in different directions?

Once that is clear, the document becomes useful because it has something real to record.

Without that, you may still get a PRD.

You just will not get the product the PRD was supposed to describe.
